為什么我得到這個 ValueError

Question

現在這是來源。 有人請幫我處理這個問題

for k in range(no_of_resc):
                name_resch = input('enter then name of the patient you want to reschedule : ')
                date_resc = input('enter the date you want to reschedule : ')
                date_for_resc = datetime.datetime.strptime(date_resc, '%Y-%m-%d %H:%M:%s')
                print('the appointment is rescheduled for ',name_resch,'and on',date_for_resc)
                resch_pat.append(name_resch)
            print('the appointment is rescheduled for :' , resch_pat)

現在現在這是 output 所以這里我有 6 個選項（忘記那些選項）當我輸入我想要預約的日期時我收到類似 ValueError 的錯誤

1 . register no.of  doctors 
2 . register no.of patients 
3 . do you want to book appointments ? 
4 . reschedule the appointments ?      
5 . cancel the appointments. 
6 . Exit 
enter your selection : 3 
enter the number of doc : 1 
enter number of patient : 1 
>> 
enter the name of the doctor : knan 
is the doctor free? (y/n) : y 
[]
['y ']
enter the name of the patient : ganesh 
['ganesh ']
lol
enter the date you want to get appointed (yyyy-mm-dd hh:mm): 2023-10-9 8:31:31

Answer 1

在此行中，您輸入帶秒數的日期：

enter the date you want to get appointed (yyyy-mm-dd hh:mm): 2023-10-9 8:31:31

但是這種模式的轉換不正確，你在這里 (c:\Desktop\vsc\JavaScript\05-Guess-My-Number\starter\doctor.py)：

date = datetime.datetime.strptime(appnt_date,'%Y-%m-%d %H:%M')

轉換應該是：

date = datetime.datetime.strptime(appnt_date,'%Y-%m-%d %H:%M:%s')
